We are in fes at the moment and have to get a bus down that way tomorrow?

We so far have planned to try to make it to Merzouga and do an evening camel trek, possibly staying in the desert and coming back the next day and then heading to Oazourate. Is this a good idea? How much should one of these treks cost.

Which is the better place to do a desert trek from?
